Couplings Omega® Elastomer Couplings

Installation
Mount one hub to shaft, leave other
hub loose for adjustment of spacing.
Place half of the Rexnord ® Omega ®
element around hubs and secure with
self-locking capscrews. Omega
element will space the other hub.
Now secure the other hub.
Mount other half of the Omega
element. Tighten all capscrews to
recommended torques below and
you’re done! Refer to the installation
instruction for further details.

Tested Tough
Rigorous testing demonstrates that
the Rexnord Omega coupling protects
connected equipment from the damaging
effects of misalignment, vibration and
gross overload. Where other coupling
designs might allow equipment
damage, the super flexible element of
Rexnord Omega couplings minimizes
the reactionary forces on equipment
bearings under severe misalignment
conditions and reduces the effects
of excessive shock overloads.

Note:
Any combination of parallel and angular misalignment which falls under the triangle
will not cause a premature fatigue failure of the flexible element in normal use.
Demonstrates coupling’s ability to
accept severe misalignment.

NOTE: Capscrews have self locking patches which
should not be reused more than twice. Capscrews can
be further used if a thread locking adhesive is applied.
Do NOT Lubricate Capscrew Threads
Important Note:
Coupling alignment is directly related to
smooth, efficient equipment operation. Care
should be taken for best possible alignment.
